Specification of Letters Patent.

Patented Mar. 14, 1922.

Application led September 6, 1918. Serial No. 252,889.

To all whom t may concern:

Be it known that I, ROBERT T. JOHNSTON, a citizen of the United States, residing at Scotch Plains, county of Union, and State of New Jersey, have invented certain new and useful Improvements in Plate Finish-v so as to economize in the space required fory the manipulation ofthe plates.

It is a further object of the invention to provide a machine in which the plates are cooled and delivered in a manner to economize space as far as possible and so that the plates may be conveniently handled by the operator.

F or a full understanding of the invention it will now be described in'connection with .the accompanyin drawings, in which,-

Fig. 1 is a si e elevation, partly broken away and partly in section, of the device, showing a plate received from a finishing mechamsm and about to be turned from horizontal to vertical position.

Fig. 2 is a view similar to Fig. 1, showing a plate being cooled, and a cooled plate delivered.

Fig. 3 is a plan view of the construction shown in Fig. 2.

Fig. 4 is a detail view partly broken away, illustrating a conventional movement. for intermittently moving the carrier.

Referring now to these drawings, the plate p to be cooled isfed to the turning mechanism in any suitable manner. In the construction illustrated, the plate is fed from a finishing mechanism consisting generally of a finishing cylinder 1, mounted in bearings 2, in a frame 3 of the machine, this frame being supported in any suitable manner (not shown).

To produce a machine occupying a minimum of space, the plate is cooled and dethe plate is fed to the delivering means and cooled while thereon. Means are further provided for turning or tipping the plate from a horizontal position in which it is fed to the turning mechanism, to a vertical position, in which it is cooled and delivered.

While the particular means employed for effecting this may be widely varied, in the particular construction illustrated, there is provided a table 4 having side guides 5, 6, to which table a late is fed on its straight edges, it being fe as shown in Fig. 1, from a finishing mechanism. This table 4 is given a downward movement tO turn the plate from its horizontal to a vertical position. In the particular construction illustrated, the table is'supported from a rock shaft T suitably mounted in bearings 8 in the frame 3 of the machine. This rock shaft is operated to lower the tableV to deliver a plate and to raise it in plate-receiving position by means of an arm 9 on the shaft to which is connected a crank arm 10 operated from a crank `11 on a driven shaft 12, suitably mounted in the frame of the machine, the shaft being drivenl from any suitable source of ower, (not shown).

The table'is periodically operated from the crank connections to gradually lower the plate, as 'shown in Fig. 2, and tO cause it to assume an upright or vertical position, in which the plate is cooled, the plate being deposited b the table onto a suitable support for cooling. In the best construction, the plate will be deposited to a support b which it may be delivered after cooling. Tlie means for effecting this may be varied. As illustrated, the plate is deposited by the table onto a travelling carrier 13. This carrier may vary in construction, but as shown includes a pair of side chains 14, 15, to which are connected supporting bars 15. The carrier chains pass over pairs of sprockets 16, these sprockets being carried on shafts 17.

The table is as shown in Figs. 1 and 2 formed with a front lip against which the edges of the plate abut, this lip keeping the plate from sliding off the table as the table is gradually lowered from the horizontal position of Fig. l, to the delivering position of Fig.2. As the table is lowered gradually the (plate gradually approaches the carrier an is gradually delivered there on, and when the parts are in the position shown in Fig. 2 the holding lip of the table is so positioned relatively to the carrier that the plate may be taken ofi the table by the cari'ienandremoved l Y- The carrier is given -an intermittent trav.- elling movement by suitable mechanism, so

,by a roller 24 on an arm Q5 carried on ay shaft 26 to which power may be applied'in anyl suitable manner, a segmental locking plate 27 being provided, which cooperates withl the locking tacesof they star wheel,

this locking plate being` carriedon the shaft.

QG. Thisineclianism isa usual one for effecting intermittent travelling .movement. in

acarrier, andin itself forms no part of the present invention.

lThe. cooling devices employed for cooling the plate may be ot" any suitable character.

Preferably they will be suclilas to coolthe` plateby -direct contact therewith with a coolingiiuid;v As illustrated, there are. pro-V vided agpair 'oit pipes 18, 19, supportedin4 anyxsuitable manner so as todirect a` supply. of Water. against the inside and theoiitside .ot the plates as thel plates stand on the carrier. y

With the andone which canibeused in combination withv a finishing vmeclialnismv., with great economy`y in space4 in the.v stereotype. room,

y v `machine shown, aY verycoinpact mechanism is provided torgcooling the. plates riesige-a which is important. lWhile the particular construction shown and described is preferred; it wWil-libe` understood that 'various changes andvariations maybe made in the details ofthis construction Without departing from the invention.

What is claimed is:

l. In a stereotype plate cooling4 and delivering device, the combination of a finishing meclianisim'a table having a iiied front stop to which table a plate is fed from the finishing mechanism in a horizontal position, a travelling carrier arranged adjacent the table, means. for gradually lowering the table with aplate thereon to turn the plate from aphorizontal to vertical position and deposit it ontlie carrier. free otwthe iront stop, and means located adjacent the carrier for. directing. a supply of coolingr fluid against both the inne'r and" outer surface ot the plate.I i v y v Y 2.
